To all 'whom 'it may concern;

Be it known that I, JOHN G. ANDREGG, a citizen of the United States, residing at Lorain, in the county of Lorain( endState of Ohio,'have invented a new and useful Improvement in Pins for Cross-Heads or' whereby the life of the same will be greatly increased:

Another object of my invention is to pro-- vide a pin which-is so constructed that the wear of ,the same can be teken up in order to prevent the pm from workmg loose.

Another object of :my invention to pro vide. a pin which is exceedingly simple and cheap in construction, and one in which the parts are so connected that alldanger of the pin becoming detached from the cross heed or clevis when in use is prevented.

A.' still further object'of my invention is to provide a pin vwhich is formed of two sections having e -tapering bore through which extends a tapering bolt for expanding said sections.

With these objects inview, the invention consists in the novel features of construction, combination and arrangement, of parts hereinafter *fully described and pointed out in the claims:

In the drawingr forming n part of this specilicetionz--Figure l is n. horizontal section through Amy improved clevis pin show ing the application ofthe same. F ig. 2 is a vertical section taken online 2'-\2 of Fig. 1. Fig. 3ds a perspective view of the pin detached. Fig. 4 1s e top plan view.

A ln carrying out my improved invention7 lf'employ a clevis A which is provided with oppositely disposed openings having beveled wells its shown et B, through which extends a pin which is formedof two sectionsvas clearly shown, and is provided with a tapering bore throughwhich extends a tapering bolt D. The pin formed by the sections is 'provided with a conical head C having e groove C? into which extends e pin E carried by the clevis .tor Vpreventing the pin from turning withinthe same, and said sec- .same firmly.

-two sections, the lower portion o the pin being exteriorly i tions are also provided with notches Cal-into which extend oppositel dis osed lugs Fl formed on the end oft 'e bo t D, whereby said boltA will also be prevented from turning Within the pin. ,The pin Gis provided with a conical ortion C* co-acting with the beveled well o 'the bore of the clevis, and 60' y terminating in e threaded portion C 'over which is arranged' e washer G which is secured in position by e nut E for locking the" rihe bolt D is o .a greater length than the. bolt C and is providedwith 6l' n threaded end D over which is arranged 'e washer I which is forced against the nut H by a nut J,- Seid nut being locked by e pin K.

extending through e-trensverse bore formedI I in the end of the bolt is clearly shown., By *its securing the pin Iwithin the elevis in this manner it is' securely held, end in suelta. manner' that the sections cen be forced apart by tightening the nut J on the bolt..

ln use the bushing M is placed ver the 75 pin between the erms. of the-Clovis which is preferably formed of steel in order t'oincrease Athe life of the pin, end is adaptedto receive the bearing. What claim is I 80 1. A clevis pin formed of two sections-i'k having e teperlng boreV and provided with n, threaded portion, a te ering boltex`tending through said tepernglbore provided with a vthreaded end', e. nut carried by the threaded 85 portion of said pin, and e nut cerriedby the threaded portion of seid bolt forelocking said pin end nut in position.

2. A clevis in longitudinally divided into evin an ,interior notch, andQO.

threaded, of e bolt of greaterlength than the pin and adapted to extend therethrough'. seid 1colt hnvinglugs adaptedv to engage seid notches, v end having a nrojetin 95 threaded portion, e. nut adapted to'wor upon the threaded portion of ther in, e.'

'washer adapted to tit over the bolt an Bear upon the pin, end e second nutedepted to work upon the thr'eededportion ofthe bolt wt and been upon seidv Washer.
